HVAC unit and wired to the DAS terminals on the
panel. If the heating temperature rises above
170° F or if the cooling temperature falls below
45° F, the sensor will cycle the equipment, while
the fan continues to run. When the system goes
out on low limit a 3 minute time delay is activated
before cooling is allowed to energize (providing
the discharge air temperature has risen above
45° F). LIMIT LED blinks when high or low limit is
reached.
Sequence of Operation:
The Green Zone™ Z-200-HC-MS is a residential /
light commercial zone control system that allows
a single HVAC unit to have up to two separate
zones. Each zone is controlled by its own space
thermostat and motorized zone damper. If a zone
thermostat calls for heating or cooling, the zone
not calling will have its damper powered closed,
and the zone calling will have its damper opened.
The heating or cooling equipment will also be
brought on at the same time. When the zone
calling is satisfied, the heating or cooling
equipment turns off. If one zone calls for heating
and another zone calls for cooling, the first zone to
call receives priority. When the first call is
satisfied, the system will changeover and take
care of the opposite call. If a zone being served
(heating or cooling) has not been satisfied within
20 minutes and an opposite call takes place, the
system will changeover. When the zone is
satisfied or 20 minutes has gone by, the system
will again changeover if an opposite call exists.
This is referred to as Auto Changeover - First Call
Priority - Time Share. In the event of a tie, cooling
will receive priority.
Ventilation Mode:
Zone ventilation is established by the individual
zone thermostat fan setting. Any thermostat set
in the fan AUTO mode will not receive ventilation
air when no equipment calls are taking place.
Any thermostat set in the fan ON mode will
receive ventilation air whenever there are no
heating or cooling calls taking place.
Power Requirements:
The Z-200 requires a separate 24 Vac
transformer. A 40 VA transformer will power the
panel and up to four (4) dampers. A 75 VA
transformer will power the panel and up to six (6)
dampers. If more than three (3) dampers for an
individual zone are required, a RY-1-HB relay
should be used with an additional properly sized
transformer. Jackson Systems HD-XXXX
rectangular and D-XX round dampers are
powered closed/spring return open. Damper
actuators are rated at 10 VA.
Wiring:
All wiring is done using conventional 18 gauge
thermostat wire. Thermostats and zone dampers
may be located up to 300 feet from the Z-200
panel.

Z-200-HC-MS Installation and Operation Instructions

Installation:
Mounting the Panel:
Carefully remove the Z-200 panel and cover
from the shipping carton. Slide the PC board out
of the snap track base and mount the base to a
flat surface either on or near the HVAC indoor
unit in an area that will facilitate easy access for
wiring. Reinstall the PC board by carefully
centering it over the base and snapping it back
into the track groves.
Wiring Zone Thermostats and Dampers:
Refer to the logic panel wiring diagram. Wire
zone 1 thermostat and its associated damper to
the ZONE 1 terminals on the logic panel. Wire
zone 2 thermostat and damper in the same
manner.
Wiring HVAC Equipment:
Wire the HVAC unit to the Z-200-HC-MS HVAC
panel terminals. Note: Do not wire the equipment
common to the Z-200-HC-MS panel.
Installing and Wiring the Z-200-DAS
Discharge Air Sensor:
Drill a ½”hole in the middle of the main discharge
air plenum approximately 18” downstream of the
heat exchanger. Remove the Z-200-DAS cover.
Slide the probe into the hole and use two selftapping sheet metal screws to secure the base
making sure that the gasket is in place. Use 18-2
thermostat wire and wire nuts to attach the
sensor leads. Replace the cover and wire the
sensor to the DAS terminals on the
Z-200-HC-MS panel.

(H). Note: Do not power the panel up until all
wiring is completed.

Test, Check and Startup:
1. Verify that all component wires have been
connected to the proper terminals and are
secure.
2. Disconnect the HVAC equipment ( R ) terminal
wire at the panel and apply 24 volts to panel.
3. Take a jumper wire and momentarily short the
DAS terminals. This will put the panel time delays
in “speed up” mode.
4. Place both zone thermostats in the OFF
position.
5. Place zone 1 thermostat in the heating mode
and have the thermostat call for heat. Confirm
that (ZD1) LED is ON and that (W) LED is ON.
Confirm that zone 1 damper is open and zone 2
damper is closed. There will be no voltage across
zone 1 (D) and (D) terminals and 24 volts on
zone 2 (D) and (D) terminals.
6. Put zone #1thermostat in the cooling mode
and have the thermostat call for cooling. Confirm
that (ZD1) LED is ON and that the (Y) and (G)
LEDs are ON. If the thermostat has internal time
delays, the cooling call may not activate
immediately.
7. Turn zone #1 thermostat off and repeat steps 5
and 6 with zone #2 thermostat. Remember, the
zone calling will have its damper open and there
will be no 24 Vac on the ‘D’ and ‘D’ terminals for
that zone.
8. Determine the ventilation mode of each zone
thermostat by setting the thermostats in the Fan
Auto or ON mode.
9. Remove 24 Volts to the panel and reconnect
the HVAC ‘R’ wire.
10. When 24 Volts is again applied to the panel,
the internal time delays will be activated.
11. Confirm that the LIMIT LED is ON. If not,
check LIMIT wiring. If the system goes out on
high or low limit, the LIMIT LED will blink.
